Just out of interest, how did the mw measure the engagement? My community midwife never tells me much and hasn't done any measurements yet. I'll be 33 weeks at the weekend.
It's not overly scientific Suej11 - she basically just has a bit of a prod and feel of the baby and what she can feel of the head. She can only feel the parts of the head that aren't engaged so it's an educated guess as far as I can tell. No actual measuring is done
It can also be confusing on your notes as you'll have a fraction written there 1/5, 2/5, 3/5 etc and I *think* that's supposed to be the part of the head that's palpable ie: not engaged, but that a lot of people confuse that to think it is how far engaged they are. Possibly some midwives note it differently too!
Anyway, they only start to consider it once they know your baby is head down so if yours wasn't in position at your last mw check she won't have checked it
